One of the answers on that post referenced Confluence, a full-sized (not personal) commercial wiki solution from Atlassian. I’ve gone to Python Meetups at Atlassian’s office here in Austin, so I thought it was worth a look. Confluence uses Java in the backend, which isn’t a technology I’m really familiar with – but our internal web hosting group here is, so they would probably be more comfortable supporting it than some alternatives. It’s just $10 (donated to charity) for up to 10 users if you host on your own server (which would be de rigueur for our process documentation, which includes login information for customer FTP sites).

I took a first look at a couple of other full-size wiki solutions:

Wagn (pronounced “wagon”) runs on Ruby on Rails. It has an interesting card-based interface that reminds me a little bit of HyperCard, which might be easier for my co-workers to wrap their minds around when I’m trying to convince them to write documentation for their own jobs. It’s open-source and free – and our web hosting group is also somewhat familiar with RoR, so it might be easier for them to support than some other alternatives, such as…

Moin Moin is a flat-file (not database) wiki built using Python 2.x (not 3.x yet). It’s the wiki software of choice for some major open-source organizations, including Apache, Ubuntu, FreeBSD, as well as Python.org itself. It’s also available in a “personal” (not web hosted) version, which would be useful to use to demonstrate the capabilities on the way to “selling” the company on the idea of hosting our documentation in a wiki (instead of files in random locations on our network file shares).
